f473d3cff9 The high bit of a Thumb2 ADR's offset is stored in bit 26, not bit 25. 
This fixes 464.h264ref with the integrated assembler.

f7d5f8a831 Fix double-free of Module. 
The ExecutionEngine constructor already added the module, so there's no
need to call addModule() directly. Doing so causes a double-free of the
Module at program termination.

b702dae9b2 Ensure that def-side physreg copies are scheduled above any other uses 
so the scheduler can't create new interferences on the copies
themselves. Prior to this fix the scheduler could get stuck in a loop
creating copies.
Fixes PR9509.

c62f168ec5 Don't coalesce identical DBG_VALUE instructions prematurely. 
Each of these instructions may have a RegsClobberInsn entry that can't be
ignored. Consecutive ranges are coalesced later when DwarfDebug::emitDebugLoc
merges entries.

free to revert and let me know how to do it.

28ebc380f6 Reapply r128045 and r128051 with fixes. 
This will extend the ranges of debug info variables in registers until they are
clobbered.

Fix 1: Don't mistake DBG_VALUE instructions referring to incoming arguments on
the stack with DBG_VALUE instructions referring to variables in the frame
pointer. This fixes the gdb test-suite failure.

Fix 2: Don't trace through copies to physical registers setting up call
arguments. These registers are call clobbered, and the source register is more
likely to be a callee-saved register that can be extended through the call
instruction.

beb7e880a2 LDRT and LDRBT was incorrectly tagged as IndexModeNone during the refactorings (r119821). 
We now tag them as IndexModePost.

90908a8eeb A8.6.399 VSTM: 
VFP Load/Store Multiple Instructions used to embed the IA/DB addressing mode within the
MC instruction; that has been changed so that now, for example, VSTMDDB_UPD and VSTMDIA_UPD
are two instructions.  Update the ARMDisassemblerCore.cpp's DisassembleVFPLdStMulFrm()
to reflect the change.

Also add a test case.

c11fb437b2 Add simple arg passing to MC-JIT and support for exit() call. 
Support argument passing simple, common, prototypes directly. More
complicated scenarios will require building up a stub function, which the
MC-JIT isn't set up to handle yet.

Add Intercept.cpp, which is just a copy from ExecutionEngine/JIT for now,
to handle looking looking up external symbol names. This probably more
properly belongs as part of RuntimeDyld. It'll migrate there as things
flesh out more fully.

e19f7261d5 Hook up the MCJIT to the RuntimeDyld library.

the MCJIT compiles and runs code, though.
